Handyman: Yes, I followed the correct upper cabinet set up as outlined in the manual. It didn’t seem right to me, so I tried different angles, but quickly went back to factory recommended settings. I guess the good folks at Wilson know what they’re doing ! LOL. It took me quite some time, maybe 2 months or so, of position tweaking to get that sweet spot that works for me. I jacked them up and removed the casters/installed the spikes. The problem now is the difficulty in trying other speakers, as the Maxx’s are just so heavy and hard to move. I do bring my Watt Puppy’s out every now and then, and place them beside the Maxx’s, and listen to them for a few days, but the placement is far from optimum. I just have to live with it, I guess. I do have a picture of the Maxx’s placement in my room, on my "Virtual System" if you care to have a look. I did not see any pictures on your profile. Wouldn’t mind seeing how you have yours placed, if possible. You also mentioned that yours are easy to move on the casters, once assembled. I assume that they are on a solid floor? Mine are on a thick pile carpet, and even with the casters, are still a real bear to move around.
